In a retrospective study, Ackland et al. (2007),
examined the factors predicting cervical collar-related pressure ulceration in major trauma
patients in a level 1 trauma center in Australia.
The results of the study showed that risk of pres-sure ulcer development due to a cervical collar in
trauma patients increased by 66% for every 1 day
increase in cervical collar time. In another study,
Ash (2002) surveyed development of pressure
ulcers in a British spinal injuries unit and reported
that 56% of patients developed a pressure ulcer
at some stage between injury and discharge from
the unit.
